Six, we can't leave now. There's that issue of trust. We did those things you said but we also promised to rebuild the country and give them a shot at governing themselves without a civil war to determine the leadership.
I think there's two basic reasons you won't hear anything from the Islamic leadership.
One: Some of them do indeed dislike us intensely. They have no condemnation to give over this killing. They support it in their hearts.
Two: What Ravs said. There are some decent folks in positions of power but they are afraid to speak out. For fear of losing influence, for fear of losing position or power. To me, this is worse than the folks in case One. If Islamic leaders are too fearful to condemn such an act for fear their followers will turn on them or that they will bring down A-Q upon themselves, well, they aren't much in the way of "leaders" then are the? They're followers and they're letting the most violent of their religion "lead" the way.
